For my needs users should be able to add more then one marker, and after I setup "custom marker group" in the ACP
users should be able to report it how many times they want.
Ex:
I (the admin) setup the "custom marker group" = Shop
User 1 reports 5 shops (Apple, amazon, ipb, microsoft, netware)
User 2 reports his location and 2 shops (Intel, AMD)
